Abstract
The purpose of this paper is to demonstrate the possibility of improving the ballistic properties of conventional gun propellants by adding fine grain metallic elements into the propellant composition or by including them as a separate component of gun charge. The primary focus is the improvement of single- and double-base gun propellants using either aluminum powder or foil. The possibility of obtaining improvements in the velocity of gun-launched projectiles has been proven theoretically by means of the thermodynamic calculations and numerical simulation of the interior ballistics process, and experimentally by firings, using 30-mm/75-caliber gun. The addition of aluminum particles into the propellant composition as well as into the gun-chamber was tested. The latter provides a rather simple method to improve the thermal characteristics of powder gases and optimize the heat-release process thereby improving the flatness of the gun pressure-time curve. This paper continues and summarizes the author's investigations published in [1,2].
